**Human-in-the-loop (HITL)** is a design pattern where a person reviews, approves, or overrides an AI agent's actions at defined checkpoints — rather than letting the agent run fully autonomously.

## Why HITL matters

Not every decision should be automated. Agents excel at interpretation and multi-step work, but they can hallucinate, misread urgency, or take irreversible actions. HITL puts humans where judgment, accountability, or legal liability require it.

## Common HITL patterns

- **Approval gates** — Agent proposes an action; human must confirm before execution (e.g., sending a refund, dispatching a contractor)
- **Escalation triggers** — Agent handles routine cases; ambiguous or high-risk cases route to a person
- **Review loops** — Agent drafts output; human edits before it goes out
- **Feedback collection** — Human corrections improve future agent behavior

## Designing HITL into architecture

HITL is not an afterthought. It belongs in the agent architecture from day one:

- Define which actions are **autonomous**, **approval-required**, or **human-only**
- Design the **handoff UX** — what context does the human see?
- Set **timeout behavior** — what happens if nobody responds?
- Track **override rates** — high override rates signal the agent needs improvement
